OIL-BURNER.-

specication of Letters Patent. Patented Nov. 171, 1919.

Application iearoctoter 1, leisg'serial no. 256,467'.

,particularly to that type which isl intended iorusing fuel oils suchas kerosene, gas oil, and the like, and also .more particularly such as are intended 4for domestic use in stoves, whether heatingY or cooking stoves.

' The object of -my invention is lto provide aburner for this kinder1 use which shall be simple in construction, durable, and easily `kept in repair, and which will secure satisfactory heating results.

In the accompanyingl drawings I have shownmy invention ina burner which is designed for insertion within vthe iire box of heatingstoves. The manner inV which the same would be modied for application `to other stoves would be evident to any mechanic. A f I Figure 1 is a plan view showing on'eburner.

Fig, 2 is avsectional side elevation of the same device.

YThe base 1,of1mydeviceis a platefwllich,

when the device is to be inserted withinr a iire pot of a stove, is made to it the same.

It is provided with a hole for each burner employed, through which air may pass freely to the burner. Such holes 10 are surrounded by upwardly extending flanges 11. Such flange 11 has two slots 12 placed diametrically opposite, in which is placed a pipe 2 which has a single discharge opening located at the point 20, the said opening constituting the nozzle for the discharge of the gas which is generated from the oil supply.

One end of this pipe is closed, as by a cap 22. The other end is connected with a vertical section 21 which in turn connects with a coiled section 23, this latter being preferably in the form of a conical helix and constituting the regenerating or .gasifying element. This latter coil section 23 is supplied through pipe 24 which in turn is connected with a pipe leading from any suitable source of supply whereby oil is delivered under sutlicient pressure to cause it to flow to Aand through these pipes. l

L 7ing within 'andsupported by the coils of the section 23 of the pipe, is e rustuni of "upon the outerV cone 3. spaceapart they two'. cones so as to form an yannularl space through which ysupplemental air may be supplied to the` point where igni- The two cones 3 and #lare -inalinement with the j etof gas discharged through the orifice 20.

a hollow cone 3. VAs shown, this has curved ides, that is, more nearly resembling a irustum oi a hyperbola.Y Within this is a Ysmaller cone 4, which `is supported away from thel cone 3 ribs 40 which, as herein shown, are secured to and kforni a part of the cone 4t, although these ribs, might as well be The `purpose'is to This is supported positionpbutrwhich rest upon the pipe, and

Fory conveniencel the platev 5 is provldedrwithran upwardly `extending lug Y 51 by whichit may be lifted when desired 01"][19035SMY- Y Y f Between the lower ends of cones 3 and L .and the, pipe; 2,in which isthe nozzle 20, is

placed a drip cup or saucer 6. This is in the nature of an annular trough which has a central hole 60. The flange 11 may have supporting arms 13 which engage the vcup (i to hold it properly placed. This cup may also rest upon the top of the pipe 2. The trough part of this cup is of such size and so placed that it lies immediately under the lower endsy of both of the cones 3 and e.

In starting the device oil may be discharged through the nozzle 20. This, if discharged with any orce, will strike the plate 5, be caught by the conical tubes 3 and 11 and will, dripping downwardly, be caught by the cup 6. Here it will burn and heat theV passes upward through the annular' passage between the conical shells B and il is supplied and assists materially in the combustion. All parts of this device are capable of being removed if desired and necessary. They are also of such construction that they are cheap to manufacture and thus may be cheaply replaced if burned out or otherwise injured.

llhat I claim as my invention is:

l. In an oil burner, in combination, a base having a draft opening therein 'surrounded by an upwardly extending iiange, said flange having two oppositely positioned pipe-receiving notches, a pipe fitting vin said notches and having a discharge orifice in its upper side placed centrally of said opening and constituting a nozzle, a conical helix of pipe placed above said parts and connected with the nozzle pipe, and a deiiecting plate supported from and spaced above the lcoiled parts of said pipe.

2. ln an oil burner, in combination, a generator comprising a conically coiled pipe having an extension extending crosswise of and beneath said coil and provided with a discharge orice forming a nozzle kdischarging centrally into said coil, a pair of nested and spaced apart conical shells supported within said pipe coils with their sinall end toward and alined with said nozzle, and a deflecting cap covering the larger end of said shells Vand spaced away therefrom to provide ilaine discharge openings about its periphery, and with said sh'ells forming a combustion chamber having double sideV walls with air passages between.y

3. In an o1l burner, 1n combination, a

generator comprising a conically coiled pipe having an extensionextending' crosswise of and beneath said coils and provided with a discharge orifice forming a nozzle discharging centrally into said coils, a pair of nested and spaced apart conical shells supported within said pipe coils with their snra'll end toward .and alined with said nozzle, a priming cup placed between the nozzle and said conical shells to catch the oil drip frorn the shells and having a central opening through which the nozzle rnay discharge.

el. In an oil burner, in combination, a generator comprising a pipe bent to form a conical heli-X and having an extension eX-k tending dianietrically of and spaced away from the smaller end of the 'coils and also having a discharge orifice 'constituting a nozzle vplaced to discharge axially into said coils, a pair 'of nested 'conical shells, the outer V'one ittin'g within 'and supported by said coils, said shells having ribs spacing thein apart yto form auxiliary draft flues, and ai lcover plate having supporting lugs maintaining it spaced above and to cover said coils, and an annular troii'gh-lile drip cup placed between Asaid shells and the nozzle with its central opening positioned to aline with the nozzle discharge, `and a base having an opening surrounded with a flange, and nie'ans for positioning and supporting said pipe and the drip cup from said flange.
